Energy and Refrigeration Use in Food SMEs: How to Capture Your Data
Energy powers every stage of food production — from field to fridge. Whether you’re running a dairy, bakery, processor, or cold-storage facility, tracking energy use is essential under the Corporate Sustainability Reporting Directive (CSRD) and the Voluntary Sustainability Reporting Standard for SMEs (VSME).
This guide explains how small and medium-sized food businesses can capture, calculate and report their energy and refrigeration data easily, using simple tools and bills they already have. For a general introduction to energy reporting, see how to report electricity use and the step-by-step guide to Scope 1 and 2 emissions.
1. Why Energy Reporting Matters
Under the CSRD (Directive 2022/2464/EU) and the VSME Basic Module, food producers are encouraged to report on:
- Total energy use (electricity, fuel, heat, etc.)
- Greenhouse gas (GHG) emissions from energy
- Energy efficiency improvements or renewable energy share
For many food SMEs, refrigeration is one of the largest energy uses — often accounting for 30–60% of total electricity consumption. Accurately tracking it helps you:
- Lower operating costs
- Demonstrate sustainability progress to customers
- Meet supplier or lender reporting requests
2. What the CSRD and VSME Standards Require
Under the CSRD
Large food manufacturers must report their Scope 1 and Scope 2 GHG emissions in line with ESRS E1 (Climate Change), including energy used in operations and refrigeration.
Under the VSME Basic Module
Smaller undertakings are asked to disclose under B3 – Energy and Greenhouse Gas Emissions:
- Total energy consumption (in MWh)
- Breakdown of renewable and non-renewable sources
- Estimated GHG emissions from energy (in tonnes CO₂e)
- GHG intensity, e.g. per euro of turnover or per tonne of product
🟢 You don’t need complex software — a simple spreadsheet and your bills will do.
3. Step-by-Step: Capturing Your Energy Data
Step 1. Collect your energy bills
Gather electricity, gas, and fuel invoices for the reporting year.
Record:
| Source | Unit | Data from |
|---|---|---|
| Electricity | kWh | Utility bills |
| Diesel / heating oil | Litres | Purchase receipts |
| LPG / natural gas | kg or m³ | Supplier invoices |
| Biomass / renewables | kWh | Meter readings or system data |
Convert everything to MWh for consistency:
1 MWh = 1,000 kWh 1 litre of diesel ≈ 0.010 MWh
Step 2. Identify refrigeration-related energy
If possible, estimate what proportion of electricity goes to cold storage, chillers, or refrigerated transport.
Simple methods:
- Separate meter: record readings for chillers/freezers.
- Equipment ratings: use power ratings (kW) × average daily hours × days per year.
- Estimate: if no metering, assume 30–60% of electricity use** for refrigeration**, depending on product type.
Example:
Total electricity: 120,000 kWh/year Estimated refrigeration share: 40% → 48,000 kWh/year
Step 3. Calculate your GHG emissions
Use standard emission factors (from national inventories or the GHG Protocol):
| Energy Type | Emission Factor | Example Calculation |
|---|---|---|
| Electricity (EU average) | 0.25 tCO₂e/MWh | 120 MWh × 0.25 = 30 tCO₂e |
| Diesel | 0.27 tCO₂e/MWh | 15 MWh × 0.27 = 4 tCO₂e |
| LPG | 0.23 tCO₂e/MWh | 10 MWh × 0.23 = 2.3 tCO₂e |
Total = 36.3 tonnes CO₂e (Scope 1 + 2)
If you use solar panels or purchase renewable energy, show this share separately under “renewable”.
Step 4. Record energy efficiency and improvements
Under B2 – Practices, policies and future initiatives, describe any progress:
- Switching to LED lighting or high-efficiency motors
- Regular refrigeration maintenance to prevent leaks
- Use of variable-speed drives or insulation
- Energy audits or cooperative energy programmes
Example:
“Installed variable-speed compressors in 2024. Estimated 10% reduction in refrigeration energy consumption.”
4. Reporting Format for Food SMEs
When you prepare your sustainability section (or VSME report), you can summarise energy and refrigeration data in a simple table:
| Metric | 2024 | 2023 | Notes |
|---|---|---|---|
| Total energy (MWh) | 135 | 142 | Lower use due to new chillers |
| Renewable energy (%) | 18% | 10% | Added rooftop solar |
| Refrigeration energy (MWh) | 55 | 60 | Based on equipment metering |
| Total GHG emissions (tCO₂e) | 35 | 39 | Calculated from energy factors |
| Energy intensity (MWh/€1m turnover) | 9 | 10 | Efficiency improved |
This is fully aligned with VSME Basic Module B3 and meets CSRD-compatible data needs.
5. Going Further: Refrigerant Leakage and Scope 1 Emissions
If your business owns or operates refrigeration systems, refrigerant leakage may count as Scope 1 emissions (direct GHG).
To capture this:
- Check F-gas maintenance records.
- Record the type and quantity of refrigerant added or replaced during servicing.
- Multiply by the refrigerant’s Global Warming Potential (GWP) to calculate CO₂e impact.
Example:
3 kg of R-404A × GWP 3,922 = 11.8 tCO₂e
Reporting this under B3 or B4 (Pollution) demonstrates transparency and supports EU climate goals.
6. Using Data for Better Decisions
Once your data is captured:
- Compare year-on-year trends.
- Identify areas for efficiency investment (e.g. insulation, cooling upgrades).
- Share highlights with customers or buyers — they value verified sustainability efforts.
- Use the same data for energy audits, grant applications, or carbon footprint tools.
7. Key Tips for Busy Food Producers
- 📅 Collect data quarterly — easier than an annual scramble.
- 🧾 Use existing invoices — no new systems needed.
- ⚡ Track renewables — solar or green tariffs count.
- ❄️ Include refrigeration separately — it’s often your biggest line item.
- 🪶 Keep it simple — focus on accuracy, not perfection.
